To ai! who in, it ni-,ay canoe/rn:

Lto it known thaty l, TIMOTHY F. Fvdlvor, a citizen ot' the United States, Pottstown, in the county ot Montgomery and State of Imnsylvania, have invented certain new and useful lmprm'ements in .Ur-raib. of whieh the followingt a epeei- Q ltfllluli.

,i While l have illustrated a particular arrangement of strengthening webs on the base l member, it is to be nnderstoml that a Wide range ol" latitude is to be permitted in this regard. and the base member may be variously shaped to give to it the necessary srengtli and durability to withstand the strains to whieh it is necessarily subjected. y 'the JForward ond of the stationary member i extends upwardly in a plane higher ithan the main portion of the stationary l member and bears directly against. the web l of the rail tl as shown at t) constituting a .f transverse platform which is provided with l tno enlargement.`v lll, and the inner faves of l the walls 4 and 5 are provided with longitndinal grom'es ll and l2 for a purpose whit-b will hereinafter appeal'.

l lhe movable member i3 comprises a body portion 13 and a head or derail block 14 l whieh is adapted to be moved onto and ott' l the rail 3. The body 22, at one end, is of ,l a width to tit between the Walls 4, el, but. at l its rear end restricted in Width so as to tit l onlargremente lf). and said movable member i# wees-sed on its under fave as shown at` 18 llo receive said enlargements 1t) when the "movable inf-:liber is in active position.y so :hat the weight of a e-nf wheel 19 on the head rves "nly to press the movable member finti lightly '.iinst the. enlargement and pr. n f any itfv'ibilitv of rearward movement ruse verhaal movement is pre-- l waited noxed that the Walls of recesses al' and that the enlargemente lil nnmher maV- ne moved rearnardly hv the vt heel fianet when no weight upon the movable irnfiber. The Weight of the enr l preventv any movement leifanse the movable member moves upwardly as well as longitudinally, but this action is readily carried out when the wheel flange engages the cam surface 22 hereinafter referred to.

The head 14 is formed with a beveled flange 20 extending from one end of the head to the center thereof to guide the wheel flanges to an inclined plane 20a on the head at the center of the head and direct said flanges over the rail, thereby derailing the same. The opposite end of the head inclines inwardly forming a tongue 2l. which extends beyond the inner surface of the head of the rail, so that a wheel approaching the device toward the tongue end of the head, will engage the beveled or cam face 22 of said tongue and force the Amovable member rearwardly without derailing as will be explained.

The Inovable member 2 is east hollow with integral walls 23 and 24 at the opposite ends of said hollow cast portion. An operating rod 25 extends through both of these Walls 23 and 24, and is screw-threaded so that it receives at its forward end a nut 26 located against the front face of Wall 23, so that when the rod is moved in one direction, it will draw the movable member from its active to its inactive position. A conical block 27 is located on the rod 25, is held against movement in one direction by lock nuts 28 on the rod, and at its larger end extends through an opening 29 in wall 24 and bears against one end of a coiled spring 30 located about the rod 25, and bearing at one end against the wall 23. A block 31 is f housed within the spring 30 on rod 25 and serves to hold the spring in its normal operative position.

.It is to be understood that the rod 25 is to be connected with apy suitable operating means so that the movable member may be moved manually from its active to its inactive position and vice versa, and when in active position is elastically held against rearward movement.

It is, of course, to be understood that the weight of a car wheel on the head 14 absolutely prevents any rearward movement by reason of the enlargements 10, but normally the spring 30 holds the movable member against rearward movement and returns said movable member to active position after a car Wheel has passed ina direction which will not derail.

The derail will be so placed upon a switch or turn-out that its tongue 21 will project toward the main track, so that if by accident the movable member is allowed to remain in active position, it .will not derail a train entering the switch or siding, but will de y rail a train on the switch or siding moving toward the main track.

It is to be understood that my derail is intended to be operated manually to move the movablegmember into active or inactive position, but in the event of an oversi t, a train can enter the turnout without eraill ment, because each wheel of the train will, by reason of contact withthe cam face 22; 70 move the movable member backwardly against the action Aof the 'spring 30, the former promptly returning the movable member t0 active position a ter the wheel is passed. .o 7;

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider 3f; myself at libert to make such changes and alterations as airly fall within the Spirits and scope of the appended claims. f
